Random rOF Fault on Motor Insight C441

The relay will be in the "rOF" state in the following scenarios (Note that the "rOF" state will be held through a power cycle) - Also note that a Reset will take the relay out of the rOF state.

  • Default state from the factory
  • The Trip button was pressed
  • The Fault Relay OFF command was given over the network (Register 400, 0x00DD)
  • By disconnecting the comm module cable connector (power was removed from the comm module as well) the relay returns to the "rOF" state. This behavior can be modified using register 441 - Comm Loss Behavior or by disabling the Network watchdog via register 400.
